Description
Technical field
Damper technical field is the utility model is related to, specially a kind of damper of external oiling concealed spring.
Background technology
Concussion when damper is mainly used to suppress to rebound after spring shock-absorbing and impact from road surface.By not level road
During face, although shock-absorbing spring can filter the vibrations on road surface, spring itself also has a reciprocating motion, and damper be exactly for
Suppress this spring jump.Damper is too soft, vehicle body will vertical bounce, damper can bring about very much too big resistance firmly,
Hinder spring normal work.In the retrofit process on suspension, hard damper will mutually arrange in pairs or groups with hard spring, and bullet
Closely bound up with car weight therefore heavier car typically uses harder damper again for the hardness of spring.The dress to connect with drawing shake bent axle
Put, for the torsional shaking (i.e. the impulsive force of bent axle subject cylinder igniting and the phenomenon that twists) for the bent axle that contends with.
But existing damper is usually provided with one group of spring or two groups of springs, it is poor damping effect to be so present,
And existing damper can not adjust the soft or hard of damper so that the immalleable different device of damper uses, in addition bullet
Spring cannot be effectively protected, and can also influence the service life of damper.
Utility model content

The bottom of post is fixedly connected with piston rod, and the bottom of the shell body, which is bolted, is provided with bottom, in the bottom
Heart position is provided with the stop collar corresponding with the piston rod position, between the piston boit and the bottom be fixedly mounted with
The damping spring of rounded distribution, the installation corresponding with the damping spring position is provided with the piston boit and bottom
Position, the top of the main body are being fixedly installed mounting blocks on shell body, and the bottom of the main body is positioned at piston rod
On be installed with lower mounting blocks.
Preferably, the outer surface of the piston boit and the smooth setting of contact surface of the cylindrical cavity.
Preferably, the stop collar cooperates with the piston rod.
Preferably, the upper and lower side of the damping spring is fixedly connected by bolt with the piston boit and bottom.
Preferably, the piston rod uses dynamic sealing with the shell body contact portion.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is fixedly connected with work by setting piston boit in outer enclosure interior activity in the bottom of piston boit
Stopper rod, the damping spring with rounded distribution being fixedly mounted between piston boit and bottom, damping spring is provided with some groups, from
And the stability of device is improved, and the cavity of compression is formed between piston boit and shell body, so as to improve the damping effect of damper,
And spring is located inside damper, the service life of damper can be improved.
2nd, the utility model can increase or decrease the radical of damping spring as needed, so that damper adapts to not
With the damping of machine, have the advantages that simple in construction, easy to use, using effect is good.
